General Description

The IXDD509 and IXDE509 are high speed high current gate

drivers specifically designed to drive the largest IXYS

MOSFETs & IGBTs to their minimum switching time and

maximum parctical frequency limits. The IXDD509 and

IXDE509 can source and sink 9 Amps of Peak Current

while producing voltage rise and fall times of less than

30ns. The inputs of the Drivers are compatible with TTL or

CMOS and are virtually immune to latch up over the entire

operating range. Patented* design innovations eliminate

cross conduction and current "shoot-through". Improved

speed and drive capabilities are further enhanced by

matched rise and fall times.

The IXDD509 and IXDE509 incorporate a unique ability to

disable the output under fault conditions. When a logical

low is forced into the Enable input, both final output stage

MOSFETs, (NMOS and PMOS) are turned off. As a result,

the output of the IXDD509 or IXDE509 enters a tristate high

impedance mode and with additional circuitry, achieves a

Soft Turn-Off of the MOSFET/IGBT when a short circuit is

detected. This helps prevent damage that could occur to

the MOSFET/IGBT if it were to be switched off abruptly due

to a dv/dt over-voltage transient.

The IXDD509 and IXDE509 are available in the 8-Pin P-DIP

(PI) package, the 8-Pin SOIC (SIA) package, and the 6-

Lead DFN (D1) package, (which occupies less than 65% of

the board area of the 8-Pin SOIC).
